SEEGIFICATION forming part of Letters Patent No. 340,446, dated April 20. 1886.

Application filed October 29, less. Serial No. 121.243. (No model.)

To all whom it may concern:

Be it known that'I, BRUNO KNIFFLER, of

' Cleveland, in the county of Guyahoga and State of Ohio, have invented new and useful Improvements in Bolting Reels; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being bad to the accompanying drawings, which form a part of this specification.

This invention relates to new and useful improvements in bolting-reels; and the invention consists in the novel construction, arrangement, and. combination of its several parts, all as more fully hereinafter described.

Figure 1 is a cross-section of my improved reel. Fig. 2 is a vertical central longitudinal section. Fig. 3 is an enlarged detail of a part corresponding with Fig. 1. Fig. 4 is a detached view of a part specially referred to. Fig. 5 is a detached and enlarged horizontal section of the feed-hopper, hollow trunnion, and its tube.

In the accompanying drawings, which form a part of this specification, A is a bolting-cylinder secured upon the shaft B. O is the inclosing-case. D is the feed-hopper. E is a little conveyer secured upon the shaft B, and arranged to carry the material from the feedhopper into the bolting-cylinder through the hollow trunnionF. 'G and H are the journals in which the shaft B is journaled. I and Jare the conveyers. is a discharge-opening for the tailings, all the aforementioned parts being of known construction and operation, except as hereinafter described.

M are a series of lifting-buckets, provided at their ends with pivots a a, by means of which they are pivotally secured in the heads of the bolting-cylinder. These liftingbuckets are placed at equal distances apart and in proximity to the bolting-cloth. They are adj nstably held in position by means of suitable clamping devices-such as the slotted rock-arm N and thumb-screw 0, (shown in detail in Fig. 3,) wherein the rock-arm N is secured to the free endof one of the pivots a of a lifting-bucket, while the thumb-screw passes through the slot b of the rock-arm (shown in Fig. 4) into the head of the bolting-cylinder, and clamps it in position thereon. It will be seen that this arrangement permits adjusting the lifting-buck- K are the cant-boards, and L P is a tube secured to the lower end of the feed-hopper, and reaching through the hollow trunnion F forms a stationary cylindrical chamber, within which the conveyer revolves and carries the material from the feed-hopper into the bolting-cylinder.

Transversely across the conveyer-boxes are placed a series of sliding drawers, R, which are provided with a hopper-shaped dischargespout, S, so arranged that .by pulling the drawers in one direction, or pushing it in the opposite, the material will be directed either into the right or left conveyer-box. This arrangement is simple, and forms a positive cut-off which can be as easily adjusted from one side of the machine as from the other, which is of importance in some mills where floor-space is limited. The drawers are provided with suitable handles (1.

T are collars provided with curved arms, by means of which they are centrally secured to the heads of the boltingcylinder, and with set-screws for securing them to the main shaft, thus making the bolting-cylinder revolve with the main shaft to which the power is applied.

In practice the buckets M in the revolutions of the bolting-cylinder carry the material some distance up on one side, and, in letting it slide off again, it is constantly agitated and kept in gentle contact with the bolting-cloth. If the buckets are provided with troughs some of the material will be carried farther on to the opposite side, and again be brought on the other side in a similar manner in contact with the bolting-cloth, thus increasing the effective area of the latter.

As before stated, the buckets 1 are not in contact with the bolting-cloth; but, on the contrary, a small distance is left between, and this distance must be increased or diminished according to the varying conditions of the material and other influences known to the prac- I CC tical miller, and with a bolting-cylinder of this description'and operation the adjustabit ity of the buckets M is an important factor for the successful operation of the machine under varying conditions. By loosening the clamping-screws O the buckets can be turned on their pivots, and adjusted to leave any desired space between them and the boltingcloth.

The advantage of making the buckets ad- IO justable on pivots, instead of adjusting them radially from or toward the bolting-cloth, which would effect the same object in View, is one of construction rather than otherwise, and I do not want to limit myself to this particular mode of adjustment, preferring it, however, as the most simple and practical one. as great difliculties attend other modes of adjustment on account of the peculiar nature of the machine.

The buckets are made somewhat shorter than the bolting-cylinder, so as to give the material at the ends freeingress and exit, and to make the adjustment of the buckets uniform I provide the rockerarms N with an indexpoint, 0, which operates inconnection with a scale.

By means of a clutch (not shown) on the main shaft, the machine can be stopped and started at will.

What I claim as my invention is- 1. In a bolting-cylinder as described, the combination, with the bolting-cylinder A, of the buckets M, having axes passing through the heads of said cylinder, slotted rock-arms N, the set-screws O, and the pinching-screws, whereby the relation between the buckets and bolting-cloth may be adjusted at will, as set forth.

2. In a bolting cylinder, the combination of a boltingcylinder, a series of buckets adj ustably secured on pivots in the heads of the bolting-cylinder, the slotted rock-arms pro vidcd with index 0, and clamping devices for holding them in their adjusted positions, substantially as described.

3. In a bolting-reel, the combination, with the bolting-reel, the buckets and their pivots, and as a means of adjnstably securing the said buckets on their pivots in the heads of the bolting-cylinder, the rock-arms N. each providedwith an aperture to receive the pivot of the bucket, and a set-screw, and a curved slot, 1), to receive a thumbscI'eW, substantially as herein shown and described.
